Galaxy Zoo

Galaxy Zoo is an online astronomy project which invites members of the public to assist in classifying over a million galaxies. The project is inspired by Stardust@home, where the public was asked by NASA to search images obtained from a mission to a comet for interstellar dust impacts. Galaxy zoo is a collaboration between Oxford University, Portsmouth University, Johns Hopkins University and Fingerprint Digital Media, Belfast.
